一种应用控制策略的方法、装置及*** 技术领域 Method, device and system for applying control strategy

本发明涉及通信领域，特别是涉及一种应用控制策略的方法、装置及***。背景技术 The present invention relates to the field of communications, and in particular, to a method, device and system for applying a control strategy. Background technique

一、策略控制和计费架构（Policy Control and Charging, PCC )。 1. Policy Control and Charging (PCC).

3GPP定义了 PCC架构，以此满足对不同的业务进行不同的 QoS ( Quality of Service, 服务质量）控制和计费需求。 3GPP TS 23.203中对 PCC架构进行了定义，参见图 1所示，其中各实体的功能描述如下： 3GPP defines the PCC architecture to meet different QoS (Quality of Service) control and billing requirements for different services. The PCC architecture is defined in 3GPP TS 23.203, as shown in Figure 1, where the functions of each entity are described as follows:

AF ( Application Function ):应用功能实体。主要为 PCRF ( Policy Control and Charging Rules Function, 策略控制和计费规则功能实体）制订策略和计费控制规则动态提供应用层会话信息，例如： IMS ( IP Multimedia Subsystem, IP多媒体子***）中的 P-CSCF ( Proxy Call Session Control Function, 代理呼叫状态控制功能）就属于 AF。 AF ( Application Function ): Application function entity. It mainly provides policy and charging control rules for the PCRF (Policy Control and Charging Rules Function) to dynamically provide application layer session information, for example: P in IMS (IP Multimedia Subsystem) -CSCF (Proxy Call Session Control Function) belongs to AF.

PCRF: 策略控制和计费控制功能实体。根据用户接入网络的限制、用户当前正在进行的应用业务信息、本地运营商配置及用户签约信息，制订相应的策略，并将策略提供给 PCEF ( Policy and Charging Enforcement Function, 策略和计费执行功能实体）执行。策略包括：业务数据流检测、 QoS 控制、门控和基于流的计费等。 PCRF: Policy Control and Charging Control Function Entity. Based on the restrictions of the user access network, the application service information currently being performed by the user, the local carrier configuration, and the user subscription information, formulate corresponding policies and provide the policy to the PCEF (Policy and Charging Enforcement Function). Entity) execution. Policies include: traffic data flow detection, QoS control, gated, and flow-based charging.

PCEF: 策略和计费执行实体。执行 PCRF下发或指定的策略，即完成对业务数据流的检测、保证业务数据流的 QoS、门控、完成在线 /离线计费以及触发与控制面的会话等功能。例如： GPRS ( General Packet Radio Service, 通用无线分组业务）中的 GGSN实体（ Gateway GPRS Support Node, GPRS网关支持节点）。 PCEF: Policy and Charging Enforcement Entity. The policy that is delivered or specified by the PCRF performs the functions of detecting the service data flow, ensuring the QoS of the service data flow, gate control, completing the online/offline charging, and triggering the session with the control plane. For example: GGSN entity in GPRS (General Packet Radio Service) (Gateway GPRS Support Node).

为了更容易理解以下流程，先阐述几个术语： To make it easier to understand the following process, a few terms are explained:

IP-CAN ( IP连接接入网 IP Connectivity Access Network ), 当用户在接入网络内漫游（位置改变时 )仍能保存 IP业务连续性（即不中断业务 ), 具有这样性质的接入网络称为 IP-CAN , 比如 GPRS网络， I-WLAN网络等； IP-CAN (IP Connectivity Access Network), when users roam within the access network (when the location changes) can still maintain IP service continuity (that is, without interrupting the service), the access network with such a nature is called For IP-CAN, such as GPRS network, I-WLAN network, etc.;

IP-CAN bearer: IP-CAN承载，具有明确速率，延迟和误比特率的 IP传输路径 (该路径指的是接入网到 GW之间），对于 GPRS来说 IP-CAN bearer对应 PDP上下文； IP-CAN bearer: IP-CAN bearer, IP transmission with clear rate, delay and bit error rate Path (the path refers to the access network to the GW), for GPRS, the IP-CAN bearer corresponds to the PDP context;

IP-CAN session: IP-CAN会话，指的是 UE (用户终端）和 PDN (分组数据网，比如 internet )标识之间的连接关系，该连接关系通过 UE的 IP地址和 UE的标识来识别。只要 UE分配了 IP地址并且能被 IP网络识别，则 IP-CAN 存在。 IP-CAN会话可以包含一到多个 IP-CAN承载。 IP-CAN session: refers to the connection relationship between the UE (User Terminal) and the PDN (Packet Data Network, such as the Internet) identifier. The connection relationship is identified by the IP address of the UE and the identity of the UE. As long as the UE is assigned an IP address and can be identified by the IP network, the IP-CAN exists. An IP-CAN session can contain one or more IP-CAN bearers.

业务数据流：一个业务数据流由包含五元组（源地址、源端口号、目的地址、目的端口号、协议）的多个 IP报文构成。用户开展的业务可以由多个业务数据流组成，例如用户开展一次多媒体通话中，一个视频流就是一个业务数据流。 Service Data Flow: A service data stream consists of multiple IP packets containing a quintuple (source address, source port number, destination address, destination port number, protocol). The user-developed service can be composed of multiple service data streams. For example, when a user conducts a multimedia call, one video stream is a service data stream.

动态 PCC规则：动态 PCC规则是由 PCRF在收到规则下发的触发信息时，根据应用业务信息、用户签约信息、运营商策略或其他策略上下文信息生成，包含了业务数据流的五元组、 QoS、门控、计费等规则内容，由规则名唯一标识动态 PCC规则。由 PCRF将规则下发给 PCEF执行。 The dynamic PCC rule is generated by the PCRF based on the application service information, the user subscription information, the operator policy, or other policy context information when the trigger information is sent by the PCRF, and includes the quintuple of the service data flow. For rule content such as QoS, gating, and accounting, the dynamic PCC rule is uniquely identified by the rule name. The rules are sent to the PCEF for execution by the PCRF.

预定义 PCC规则：预定义 PCC规则预配置在 PCEF上，并且在 PCRF上保存有相应的规则名，当 PCRF收到规则激活的触发信息时，由 PCRF将包含该规则名的激活指令下发 PCEF, 指示 PCEF激活预定义 PCC规则。 Pre-defined PCC rules: Pre-defined PCC rules are pre-configured on the PCEF, and the corresponding rule names are saved on the PCRF. When the PCRF receives the trigger information for the rule activation, the PCRF sends the activation command containing the rule name to the PCEF. , instructs the PCEF to activate the predefined PCC rules.

Rule);

9、 GW安装规则，并根据规则打开或者关闭对应的业务数据流，保证相应的 QoS,如果 GW执行 P-CAN承载和规则绑定，则由 GW根据规则要求选择一个合适的 IP-CAN承载，否则 GW根据 PCRF的 PCC规则和 IP-CAN承载标识的绑定关系，在对应的 IP-CAN承载上执行规则； 9. The GW installs the rules, and opens or closes the corresponding service data flow according to the rules to ensure the corresponding QoS. If the GW performs the P-CAN bearer and the rule binding, the GW selects an appropriate IP-CAN bearer according to the rule requirements. Otherwise, the GW executes the rule on the corresponding IP-CAN bearer according to the binding relationship between the PCC rule of the PCRF and the IP-CAN bearer identifier;

参见图 3所示为用户侧发起的 IP-CAN承载建立流程图，包括下列步骤： Referring to FIG. 3, a flow chart of establishing an IP-CAN bearer initiated by the user side includes the following steps:

1、 GW接收到 UE发起的 IP-CAN承载建立请求消息，对于 GPRS, 即建立第一个 PDP上下文； 1. The GW receives the IP-CAN bearer setup request message initiated by the UE, and establishes a first PDP context for GPRS;

2、 GW通知 PCRF IP-CAN 载建立， GW创建一个新的 DCC ( Diameter信用控制）会话，向 PCRF发送 CCR消息，包含 UE标识和 IP地址。如果 PCRF 执行 IP-CAN承载和规则绑定，则 GW还要上报 IP-CAN承载标识； 2. The GW notifies the PCRF that the IP-CAN is set up.

13、 GW向 UE返回 IP-CAN承载建立响应消息。 13. The GW returns an IP-CAN bearer setup response message to the UE.

上述 IP-CAN会话和 IP-CAN承载的建立流程主要用于说明：当用户建立了 IP-CAN会话之后，就可以开展业务。业务包含的每个业务数据流由于在 QoS 或计费等规格上存在区别，因此需要在用户 IP-CAN会话下建立不同的 IP-CAN 承载来传输不同的业务数据流；以及需要 PCC架构为每个业务数据流分别建立策略，并应用于相应的 IP-CAN承载上。而由于不同的用户有不同的 IP-CAN会话，因此如果多个用户开展业务， PCC 架构需要分别为每个用户建立独立的策略控制机制。 The establishment process of the above IP-CAN session and IP-CAN bearer is mainly used to explain: After the user establishes an IP-CAN session, the service can be started. Each service data stream included in the service differs in specifications such as QoS or billing. Therefore, different IP-CAN bearers need to be established under the user IP-CAN session to transmit different service data streams; and the PCC architecture is required for each Each service data flow is separately established and applied to the corresponding IP-CAN bearer. Since different users have different IP-CAN sessions, if multiple users conduct business, the PCC architecture needs to establish separate policy control mechanisms for each user.

发明人在实现本发明过程中发现，现有 PCC机制规定了用户开展业务时，为每个用户建立独立的策略控制机制。而在实际应用中，存在着对多个用户开展的业务采取相同策略控制的情况。例如：上网业务中对受限网站需要禁止访问，当 PCC检测到任何用户访问受限网站时，就要采取相同的策略拒绝用户开展此业务；又如：很多用户采取包月付费的方式体验数据应用业务，对于包月付费用户开展业务， PCC 可以采取相同的计费策略；再如：对于和网络运营商签约规格相同的用户， PCC可采用相同的 QoS控制策略。 In the process of implementing the present invention, the inventors found that the existing PCC mechanism stipulates that when a user conducts a service, an independent policy control mechanism is established for each user. In practical applications, there are situations in which the same policy control is applied to the services carried out by multiple users. For example: In the Internet service, restricted access is required for the restricted website. When the PCC detects that any user accesses the restricted website, the same policy is adopted to deny the user to carry out the service. Another example: Many users use the monthly subscription fee to experience the data application. For the service of the monthly subscription user, the PCC can adopt the same charging policy. For another example: For users with the same contracting specifications as the network operator, the PCC can adopt the same QoS control policy.

综上，现有 PCC机制实现了对每个用户开展的业务分别建立独立的策略控制机制，如果用现有机制满足上述应用情况时，就会导致策略控制效率低下、策略维护和管理复杂等问题，无法满足同一策略控制多用户开展业务的需求。 In summary, the existing PCC mechanism implements an independent policy control mechanism for each user's business. If the existing mechanism is used to satisfy the above application, it will lead to inefficiency in policy control, policy maintenance, and complex management. , unable to meet the same policy to control the needs of multiple users to conduct business.

针对多用户开展业务时可采取相同控制策略的需求，本发明提供了一种应用控制策略的方法、装置及***，使得对策略需求相同的用户可以共享控制策略，从而达到筒化控制、提高控制效率、减少策略管理和维护复杂度的目的。本发明实施例提供的一种应用策略控制的方法，参见图 4所示，包括下列主要步骤： The present invention provides a method, device, and system for applying a control policy, so that users with the same policy requirements can share control policies. Slightly, to achieve the purpose of centralized control, improve control efficiency, reduce policy management and maintenance complexity. A method for applying policy control according to an embodiment of the present invention, as shown in FIG. 4, includes the following main steps:

51、 PCEF获得控制策略的应用范围信息； 51. The PCEF obtains the application scope information of the control strategy;

52、 PCEF根据控制策略的应用范围信息在该控制策略的应用范围内应用该控制策略。 52. The PCEF applies the control policy within the application scope of the control policy according to the application scope information of the control policy.

具体的，包括下述内容： Specifically, it includes the following:

所述的控制策略应用范围具体指多用户的 IP接入会话。所述多用户可以指用户组内用户，也可以指网络***内的用户。如果控制策略应用范围的信息指示应用于用户组，则对用户组内所有或部分用户开展的业务实施相同的控制策略；如果控制策略应用范围的信息指示应用于网络***，则对 PCEF对应网络系统中的所有或部分用户开展的业务实施相同的控制策略。 The application scope of the control policy specifically refers to an IP access session of multiple users. The multiple users may refer to users in the user group, and may also refer to users in the network system. If the information indicating the application scope of the control policy is applied to the user group, the same control policy is implemented for all or part of the users in the user group; if the information indicating the application scope of the control policy is applied to the network system, the PCEF corresponding network system The business of all or part of the users in the implementation of the same control strategy.

基于 PCC架构，所述 PCEF获得控制策略的应用范围信息的方式为下列之方式一：采用预定义 PCC规则描述控制策略。 Based on the PCC architecture, the manner in which the PCEF obtains the application scope information of the control policy is the following manner: The control strategy is described by using a predefined PCC rule.

首先在 PCEF上预定义 PCC规则，但没有设定该预定义 PCC规则的应用范围。之后在 PCRF收到下发控制策略的触发信息时， PCRF向 PCEF下发激活预定义 PCC规则的指示信息（即预定义控制策略的应用范围指示信息 ),所述指示信息中包含该预定义 PCC规则的应用范围信息，用于指定预定义 PCC规则应用于用户组还是应用于网络***。一个示例如下： The PCC rules are first predefined on the PCEF, but the application scope of the predefined PCC rules is not set. After the PCRF receives the triggering information of the control policy, the PCRF sends the indication information of the predefined PCC rule (that is, the application scope indication information of the predefined control policy) to the PCEF, where the indication information includes the predefined PCC. The application scope information of the rule, which is used to specify whether the predefined PCC rules are applied to the user group or to the network system. An example is as follows:

Charging-Rule-Install：: = < A VP Header: 1001 > Charging-Rule-Install:: = < A VP Header: 1001 >

* [ Charging-Rule-Name ] * [ Charging-Rule-Name ]

[ Rule- Regulate- Info ] [ Rule- Regulate- Info ]

Rule-Regulate-Info：: = < A VP Header: xxx> Rule-Regulate-Info:: = < A VP Header: xxx>

[ Usergroup- Requirement ] [ Usergroup- Requirement ]

[ System- Requirement ] [ System- Requirement ]

Rule-Regulate-Info AVP表示 PCC规则的应用范围信息， Grouped型。在 Charging-Rule-Install AVP中如果不包含 Rule-Regulate-Info AVP, 则表示该策略应用于单用户。 Rule-Regulate-Info AVP indicates the application scope information of the PCC rule, Grouped type. in If the Rule-Regulate-Info AVP is not included in the Charging-Rule-Install AVP, the policy is applied to a single user.

Usergroup-Requirement AVP表示 PCC规则应用于用户组， OctetString型；该 AVP的取值可以是用户组标识，或者是用户组下的所有或部分用户的地址列表。 Usergroup-Requirement AVP indicates that the PCC rule is applied to the user group, OctetString. The value of the AVP can be the user group ID or the address list of all or some users under the user group.

System-Requirement AVP表示 PCC规则应用于网络***， OctetString型。方式二：采用动态 PCC规则描述策略。 System-Requirement AVP indicates that the PCC rule is applied to the network system, OctetString type. Method 2: Use dynamic PCC rules to describe the policy.

PCRF 收到下发策略的触发信息时，根据运营商策略、用户签约信息和 /或其他策略上下文信息， PCRF生成动态 PCC规则向 PCEF下发，并且随该 PCC 规则还下发该 PCC规则的应用范围指示信息，在该指示信息中包含该 PCC规则的应用范围信息。其示例可参考方式一中示例的描述。 When the PCRF receives the triggering information of the policy, the PCRF sends the dynamic PCC rule to the PCEF according to the operator policy, the user subscription information, and/or other policy context information, and the PCC rule is also delivered with the PCC rule. The range indication information includes the application scope information of the PCC rule in the indication information. An example of this can be referred to the description of the example in the first mode.

方式三、采用预定义 PCC规则描述控制策略，并设定该控制策略的应用范围。 Method 3: Use a predefined PCC rule to describe the control strategy and set the application scope of the control policy.

首先在 PCEF上预定义 PCC规则，并设定该预定义 PCC规则的应用范围信息。之后在 PCRF收到下发控制策略的触发信息时， PCRF向 PCEF下发激活预定义 PCC规则的指示信息，所述指示信息包含规则名，只用于激活特定的 PCC 规则。由于已经设定了 PCC规则的应用范围，所以在该 PCC规则被激活时，也就限定了该 PCC规则的应用范围。 First, the PCC rules are predefined on the PCEF, and the application scope information of the predefined PCC rules is set. Then, when the PCRF receives the triggering information of the control policy, the PCRF sends the indication information for activating the predefined PCC rule to the PCEF, where the indication information includes the rule name, and is only used to activate the specific PCC rule. Since the application range of the PCC rule has been set, when the PCC rule is activated, the application range of the PCC rule is also limited.

在上述三种方式中，如果所述 PCC规则的应用范围信息指示应用于用户组，则将所述控制策略应用于用户组内所有或部分用户对应的 IP-CAN会话上；如果所述控制策略应用范围的信息指示应用于网络***，则将策略应用到网络*** 内所有或部分用户对应的 IP-CAN会话上。 In the above three manners, if the application scope information indication of the PCC rule is applied to a user group, the control policy is applied to an IP-CAN session corresponding to all or part of users in the user group; if the control policy The application scope information indication is applied to the network system, and the policy is applied to the IP-CAN session corresponding to all or some users in the network system.

具体对应方式一、 PCEF根据 PCC规则的应用范围信息，需要将预定义 PCC 规则激活应用到相应的 IP-CAN会话上。 Specific Corresponding Method 1. The PCEF needs to apply the predefined PCC rule activation to the corresponding IP-CAN session according to the application scope information of the PCC rule.

具体对应方式二、 PCEF根据 PCC规则的应用范围信息，需要将动态 PCC 规则安装应用到相应的 IP-CAN会话上。 Specific Corresponding Method 2: According to the application scope information of the PCC rule, the PCEF needs to install and apply the dynamic PCC rule to the corresponding IP-CAN session.

具体对应方式三、 PCEF需要将预定义 PCC规则激活应用到为该预定义 PCC 规则设定的应用范围所对应的 IP-CAN会话上。本发明实施例还提供了一种策略和计费执行功能实体（PCEF ), 参见图 5 所示，其包括：获得单元 51和执行单元 52。 Specifically, the PCEF needs to apply the predefined PCC rule activation to the IP-CAN session corresponding to the application range set for the predefined PCC rule. The embodiment of the present invention further provides a policy and charging execution function entity (PCEF), as shown in FIG. 5, which includes: an obtaining unit 51 and an executing unit 52.

以下通过 4个实施例进一步描述。 The following is further described by four embodiments.

实施例一：利用网络***级策略实现策略控制。 Embodiment 1: Implementing policy control by using a network system level strategy.

对于访问受限网站， PCC对所有用户采取相同的策略。具体实现可以通过在 PCEF上为所有使用该 PCEF的用户 IP-CAN会话对应的 IP-CAN承载配置网络***级策略规则，该规则中包含受限网站的地址信息。一旦任何用户访问该受限网站，包含受限网站地址信息的业务数据流需要使用 IP-CAN承载传输时，应用到 IP-CAN承载的网络***级 PCC规则，检测到该业务数据流与该规则匹配，则采取 "关闭" 的门控策略，禁止用户访问。这种策略实现机制，显然筒化了控制复杂度，避免为每个用户独立生成策略而带来控制效率的下降。使用网络***级策略对用户业务进行策略控制的流程，参见图 9所示包括下列步骤： For access restricted sites, PCC adopts the same policy for all users. The specific implementation may be configured by configuring a network system level policy rule on the PCEF for all IP-CAN bearers corresponding to the IP-CAN session of the user using the PCEF, where the rule includes the address information of the restricted website. Once any user accesses the restricted website, the service data stream containing the restricted website address information needs to be transmitted using the IP-CAN bearer, and the network data level PCC rule applied to the IP-CAN bearer detects the service data flow and the rule. If it matches, the "close" gating strategy is adopted to prohibit user access. This kind of policy implementation mechanism obviously controls the control complexity and avoids the control efficiency drop caused by independently generating policies for each user. The process of using the network system level policy to control the user's business policy, as shown in Figure 9, includes the following steps:

1、在 PCEF上配置预定义的 PCC规则，并在 PCRF保存对应的规则名；预定义 PCC规则中的目的地址信息为 A · B · C · D(http：〃 www.abcd.com)。 1. Configure the predefined PCC rules on the PCEF and save the corresponding rule names in the PCRF. The destination address information in the predefined PCC rules is A · B · C · D (http: 〃 www.abcd.com).

The PCRF sends a Charging-Rule-Install AVP with a predefined PCC rule name to the PCEF with a Diameter CCR or RAR message, indicating that the specified predefined rule is activated. The Charging-Rule-Install AVP also includes the policy application range indication information. The format of the delivery policy and policy application scope information is as follows:

* [ Charging-Rule-Name ] * [ Charging-Rule-Name ]

[ Rule-Regulate-Info ] [ Rule-Regulate-Info ]

6、 PCEF根据网络***级 PCC规则，对业务数据流进行检测，感知业务数据流中的目的地址信息 (http://www.abcd.com)与网络***级 PCC规则中包含的地址信息 (A . B . C . D)相同，执行 "关闭，，的门控策略。 6. The PCEF detects the service data flow according to the network system level PCC rule, and perceives the destination address information (http://www.abcd.com) in the service data flow and the address information included in the network system level PCC rule (A) B. C. D) Same, perform the "close," gating strategy.

7、 PCEF拒绝用户业务。 7. PCEF rejects user services.

实施例二：利用用户组级策略实现策略控制（用户组由用户组标识表示）众多用户使用数据业务都采取包月付费的方式， PCC 在对这些包月付费用户开展业务时可采用相同的计费策略。具体实现可以通过 PCRF按照运营商的策略（比如所有包月付费用户为一个用户组，运营商为该用户组赋予一个组标识）生成动态的用户组级 PCC规则并下发给 PCEF, PCEF将该用户组级 PCC 规则应用到用户组标识所指的所有用户对应的 IP-CAN会话上。当组内用户开展业务时，就可采取相应的计费方式。使用用户组级策略对用户业务进行策略控制的流程，参见图 10所示包括下列步骤： Embodiment 2: Implementing policy control by using user group level policies (user groups are represented by user group identifiers) Many users use data services to adopt monthly payment methods, and PCC can adopt the same charging policy when conducting business for these monthly subscription users. . The specific implementation can generate a dynamic user group-level PCC rule and send it to the PCEF through the PCRF according to the policy of the operator (for example, all the monthly subscription users are a user group, and the operator assigns a group identifier to the user group). The group-level PCC rules are applied to the IP-CAN sessions corresponding to all users indicated by the user group identifier. When users in the group conduct business, they can adopt the corresponding charging method. The process of policy control of user services using user group-level policies, as shown in Figure 10, includes the following steps:

The PCRF generates a user group-level dynamic PCC rule according to the policy context information such as the operator policy. The PCRF sends the Charging-Rule-Install AVP containing the dynamic PCC rule information to the PCEF by using the Diameter CCR or RAR message. The Charging-Rule-Install AVP contains the policy application scope indication information. The delivery policy and policy application scope indication information are in the following form:

* [ Charging-Rule-Name ] * [ Charging-Rule-Name ]

[ Charging-Rule-Definition ] [ Charging-Rule-Definition ]

[ Rule-Regulate-Info ] [ Rule-Regulate-Info ]

[ Usergroup-Requirement ] 其中 Charging-Rule-Name AVP 用于表示下发的 PCC 规则名； Charging-Rule-Definition AVP用于表示 PCC规则信息； Rule-Regulate-Info AVP 包含的 Usergroup-Requirement AVP用于指示下发的 PCC规则应用于用户组，以用户组标识（ 12345678 )表示，对用户组内的所有用户开展业务实施相同的计费策略。 [ Usergroup-Requirement ] The Charging-Rule-Name AVP is used to indicate the issued PCC rule name.

实施例三：利用用户组级策略实现策略控制（用户组由用户组列表表示）运营商可以将同一等级的用户划分为一个用户组，对该用户组下的所有用户开展业务实施相同的 QoS控制策略。具体实现可以通过 PCRF根据运营商策略生成相应的用户组级 PCC规则下发给 PCEF, PCEF将该用户组级 PCC规则应用到用户组列表所指的所有用户的 IP-CAN会话上。使用用户组级策略对用户业务进行策略控制的流程，参见图 11所示包括下列步骤： Embodiment 3: Implementing policy control by using user group level policies (user groups are represented by user group list) The operator can divide users of the same level into one user group, and implement the same QoS control for all users in the user group. Strategy. The specific implementation may be performed by the PCRF to generate a corresponding user group level PCC rule according to the operator policy, and the PCEF applies the user group level PCC rule to the IP-CAN session of all users indicated by the user group list.
